Bioinspired Hierarchical Surface Structures with Tunable Wettability for Regulating Bacteria Adhesion

“…Ultra-violetÀvisible (UVÀvis) spectra of both diluted G1 and G2 nanofibrous gels gave rise to the absorbance maximum at the wavelength of 250À258 nm, indicative of πÀπ* transitions in the benzene groups (Figure S4). 42 Circular Dichroism (CD) spectra show distinct trough near 200 nm (ππ* transition, characteristic peak of random coil) and less pronounced trough near 240 nm (nπ* transition), suggesting β-turn-like arrangements (Figure 2a). 43 The Small Angle X-ray Scattering (SAXS) patterns of G1 and G2 xerogels (Figure 2b) reveal the crystalline nature of the fibrillar networks and polymorph arrangements in the fibers.…”

Wettability of Supramolecular Nanofibers for Controlled Cell Adhesion and Proliferation

“…Optical spectroscopy was utilized to probe the conformation of the conjugated moiety within the nanofibers. UV–vis spectra of all gels gave rise to absorbance maximum at 250 nm, indicative of π–π* transitions in the benzene groups (Figure a) . CD spectra revealed the formation of random conformations (distinct trough near 198 nm) and β-turn-like structures (pronounced trough at 240 nm) within M1–M3 fibers (Figure b) …”

“…UV−vis spectra of all gels gave rise to absorbance maximum at 250 nm, indicative of π−π* transitions in the benzene groups (Figure 5a). 36 CD spectra revealed the formation of random conformations (distinct trough near 198 nm) and β-turn-like structures (pronounced trough at 240 nm) within M1−M3 fibers (Figure 5b). 37 Contact angle (CA) measurement was used to test the wettability of M1−M3 xerogels.…”

Morphoanatomical Studies of Tiliacora racemosa Colebr.

“…The plant has also been used in many Ayurvedic preparations [11]. Various phytochemical investigations have also been carried out resulting in isolation and identification of esters [12] and bisbenzylisoquinoline alkaloids [13].…”
